Ok, I made them try for a baby, but I don't know the result yet.
Christopher's and their son's birthdays came on the same day and Christopher is now an elder. I don't know if men make babies after being elders or not. (So I hope my female sim is pregnant now, anyway.)
Christopher wishes to retire (he does not make good money from his work anyway), so I think iIshould allow him to retire, but how can i do that ? And can I make him work on something in home? He's not artistic, so I don't think I should make him paint or play guitar. I saw in some topics here that the Sims can work on gardening, but I don't know how!
